BerkeleyDB Description

Perl extension for Berkeley DB version 2, 3 or 4 BerkeleyDB is a Perl module that provides an interface to most of the functionality available in Berkeley DB versions 2, 3 and 4. In general it is safe to assume that the interface provided here to be identical to the Berkeley DB interface. The main changes have been to make the Berkeley DB API work in a Perl way. Note that if you are using Berkeley DB 2.x, the new features available in Berkeley DB 3.x or DB 4.x are not available via this module.SYNOPSIS use BerkeleyDB; $env = new BerkeleyDB::Env ; $db = tie %hash, 'BerkeleyDB::Hash', ; $db = new BerkeleyDB::Hash ; $db = tie %hash, 'BerkeleyDB::Btree', ; $db = new BerkeleyDB::Btree ; $db = tie @array, 'BerkeleyDB::Recno', ; $db = new BerkeleyDB::Recno ; $db = tie @array, 'BerkeleyDB::Queue', ; $db = new BerkeleyDB::Queue ; $db = new BerkeleyDB::Unknown ; $status = BerkeleyDB::db_remove $status = BerkeleyDB::db_rename $status = BerkeleyDB::db_verify $hash{$key} = $value ; $value = $hash{$key} ; each %hash ; keys %hash ; values %hash ; $status = $db->db_get() $status = $db->db_put() ; $status = $db->db_del() ; $status = $db->db_sync() ; $status = $db->db_close() ; $status = $db->db_pget() $hash_ref = $db->db_stat() ; $status = $db->db_key_range(); $type = $db->type() ; $status = $db->status() ; $boolean = $db->byteswapped() ; $status = $db->truncate($count) ; $status = $db->compact($start, $stop, $c_data, $flags, $end); $bool = $env->cds_enabled(); $bool = $db->cds_enabled(); $lock = $db->cds_lock(); $lock->cds_unlock(); ($flag, $old_offset, $old_length) = $db->partial_set($offset, $length) ; ($flag, $old_offset, $old_length) = $db->partial_clear() ; $cursor = $db->db_cursor() ; $newcursor = $cursor->c_dup(); $status = $cursor->c_get() ; $status = $cursor->c_put() ; $status = $cursor->c_del() ; $status = $cursor->c_count() ; $status = $cursor->c_pget() ; $status = $cursor->status() ; $status = $cursor->c_close() ; $cursor = $db->db_join() ; $status = $cursor->c_get() ; $status = $cursor->c_close() ; $status = $env->txn_checkpoint() $hash_ref = $env->txn_stat() $status = $env->setmutexlocks() $status = $env->set_flags() $status = $env->set_timeout() $status = $env->lsn_reset() $txn = $env->txn_begin() ; $db->Txn($txn); $txn->Txn($db1, $db2,...); $status = $txn->txn_prepare() $status = $txn->txn_commit() $status = $txn->txn_abort() $status = $txn->txn_id() $status = $txn->txn_discard() $status = $txn->set_timeout() $status = $env->set_lg_dir(); $status = $env->set_lg_bsize(); $status = $env->set_lg_max(); $status = $env->set_data_dir() ; $status = $env->set_tmp_dir() ; $status = $env->set_verbose() ; $db_env_ptr = $env->DB_ENV() ; $BerkeleyDB::Error $BerkeleyDB::db_version # DBM Filters $old_filter = $db->filter_store_key ( sub { ... } ) ; $old_filter = $db->filter_store_value( sub { ... } ) ; $old_filter = $db->filter_fetch_key ( sub { ... } ) ; $old_filter = $db->filter_fetch_value( sub { ... } ) ; # deprecated, but supported $txn_mgr = $env->TxnMgr(); $status = $txn_mgr->txn_checkpoint() $hash_ref = $txn_mgr->txn_stat() $txn = $txn_mgr->txn_begin() ; Requirements: · Perl
